Abstract
A cylinder head gasket for internal combustion engine, which comprises a gasket body formed with hole for combustion chambers and holes for coolant passages is disclosed, in which protruded portions of high thermal conductivity metal whose thickness is larger than the thickness of the gasket body are provided around the hole for combustion chamber and elastic seal members whose thickness is larger than the thickness of the protruded portions are provided around each of the holes for coolant passages. The gasket body may be made of a metal of high thermal conductivity. In case where the gasket body is made of a material permeable to liquid, the seal members may be provided such that they cover peripheral walls of the holes for coolant passages, respectively.
